Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed January 14, 1911. Serial No. 602,594.

To @ZZ whom it may concern:

Be it known that I, GEORGE F. CoATEs, a citizen of the United States, and aresident of Rutherford, county of Bergen, and State of New Jersey, have invented a new and useful Device tov be Used in Monotype-Ma- .chines, of which the following is a full,

clear, and exact specification.

My invention is`for use solely in the machine for preparing the ribbon which is intended for use in the casting machine, and its object is the devising of means whereby the paper nibs, punched from Vthe ribbon in the process of perforating it, may be removed in the least possible time from the chamber provided for collecting them and transferred to the receptacle'forming a part of my device, the removal of the nibs being accomplished by means of pneumatic power.

Referring to the drawings forming part of this specification, Figure l is a sectional elevational view of my nib extractor in position upon the ribbon perforating machine shown in fragmental v sectional elevation. Fig. 2 is a sectional view through the line x-az of Fig. l showing additional parts of the perforat-ing machine. Fig. 3 is a full size view of my device looking upward from the bottom, and Fig. 4 is a full size view of the lower part shown in Fig. l.

The monotype casting machine includes i two distinct machines, namely', the casting machine proper, and the machine for preparing the perforated ribbon used in the casting machine.

rFhe casting machine is mainly controlled by a continuously traveling perforated ribbon. The perforations in the ribbon effect an operation A of pneumatically controlled mechanisms which accomplish the desired ultimate results above enumerated.

The ribbon preparing machine is for the purpose of perforating the ribbon in a manner such that when it is used with the cast-- ing machine the desired matter will be cast.

My invention has only to do with the ribbon preparing machine.

The machine has a keyboard which is operated much as a typewriter. The depressing of the keys effect a raising and.' lowering ofa series of perforating or punchinggneedles which, as they are forcedr upward, 'perforate the ribbon passing in front of them. The needles are positioned in a row transversely of the ribbon, and puncture it in a correspondingly transverse direction. f

Only suiiicient of the ribbon preparing (or keyboard) machine is shown in the accompanying drawings to clearly understand the purpose of my invention and the manner of using it.

The ribbon 1 is made of paper' wound in a roll 2 and has along each of' its edges 'a row of perforations 3. The paper' roll is mounted on a shaft 4 and is fed therefrom to a spool 5. The intermediate strip of ribbon between the roll and spool moves around the lower side of a stationary cylinder 6. The cylinder is hollow to afford a chamber 7 through which extends a shaft 8 having ends projecting through the endsof the cylinder. On these ends are mounted spur wheels 9 provided with the peripheral spurs or pins 10. The ribbon passes around the lower side of these wheels and the perforatio'ns 3 formed therein are engaged by the spurs. The wheels are positively driven which effects an accurate and constant feeding ofthe ribbon. The shafts 4 and- 8 and i spool 5 are journaled in the sides 11 ofthe frame and the cylinder is secured to semicylindrical lugs` 12 forming part of the frame. Y

Beneath the cylinder lis a system of punching needles 13 projecting from the ends of punching bars 14. The needleshave their upper ends resting inholes 15 formed in the f punching needles as they are being raised by the operator at the keyboardl (not shown) to pass through the paper ribbon traveling above them and to punch therefrom a small paper disk or nib. The movement of the punchers is suicient to bring their ends through the holes 17 inthe cylinder to permit them to carry thel paper nib punched from the ribbon in the chamber7 and there deposit it. It does not take long before this chamber is sufficiently filled with nibs to require cleaning. My invention vis devised purely toimprove the manner of accomplishing this. j y

The chamber 7'is provided at the top with a large opening 18 and itis through this opening that my devicepperates to extract the nibs. They are removed almost instantaneously from the chamber to my device without any possibility of scattering the nibs about the machine. Moreover when using my nib extractor one person may be delegated. to take it periodically to each machine in use and remove the nibs. The operator at the keyboard need not stop his work while this is being done.

AA pipe or flexible hose in connection with a supply of compressed air is generally hangino' near each machine. This is represented in the drawings b v the fragmental piece of rubber tubing 19. The operator uses this hose for cleaning his machine from dust, stray paper nibs, etc., and a cock is provided for turning on or olf the compressed air as desired. I make use of this hose and the compressed air for forcing the nibs from the chamber T into the receptacle of the extractor'. It is on account of the availability of the compressed air and easily accessible tube that I make use of it as a means for removing the nibs. It is however equally possible to remove the nibs by reversing the operation and to use an air suction pipe to draw them into my receptacle instead of forcing them in by compressed air. Such a change however would require certain rearrangements and slight changes of the parts of my invention, which will later be pointed out. As just remarked, it is the availability of the compressed air already in use at the machines that makes it expedient to devise mechanism suitably adapted for its use. Should it subsequently be the custom to clean the machines by a suction of air instead of compressed air, it would then be necessary to change my extractor to make available the suction pipes.

kMy invention comprises a receptacle a for receiving the nibs. It may conveniently be a comparatively large vertical cylindrical sheet metal box open at the top. It has a ring b at the top for hanging it up when not in use to protect the parts at the base from injury. It is preferably large enough to hold the nibs from many machines so that it need not be emptied oftener than is reasonable. A cover c is provided for the box to securely retain the nibs therein. The nibs are forced into the box with the inrush of air, and itis necessary that the air should leave the box while the nibs are retained, therefore an outlet for the air is necessary. I prefer to make this in the cover as it will there be farthest away from the mass of collecting nibs gradually rising in the receptacle. I accordingly provide the cover with a large opening Z and to prevent the escaping of the nibs I cover the hole with a fine wire mesh e. The cover preferably has a flange f for holding it on the box but other forms may be used. A tube g is secured through a hole in the bottom of the receptacle and is intended to afford communicationk between the chamber 7 and receptacle a ign'l order to provide a passageway for conveying the nibs. It extends through the receptacle to a point near the top. This enables the nibs passing therefrom to gradually settle in the bottom of the receptacle without being unnecessarily agitated by the inrushing air. The tube extends suthciently below the receptacle to raise it clear from the working parts of the machine and terminates in a plate z' which is curved to cover the opening 18 to make a substantially airtight fit.

The tube g should be closed when not in use to prevent any of the nibs in the receptacle from escaping therethrough. The closure may be made by a valve normally closed and only opened by the pressure of the air passing through the tube. IVhere the tube extends to a point near the top of the receptacle as in my preferred construction, it is desirable to use a continuously open tube when in position for use'and a closed tube when out of position. I accordingly provide the following mechanism: Within the tube is secured a pair of sleeves j through which is passed a rod 7c. The rod extends the entire length of the tube and for a suitable distance below it. Its upper end is bent over and has secured thereon a disk Z adapted to completely cover the top of the tube when the extractor is not in use. A helical spring m is mounted on the rod having its upper end secured to the rod and its lower end secured to the tube. is under tension to continually hold the disk or cover down when not in use. The lower end of the rod is bent over and turned to form a ring n. This sets upon the shaft S when the extractor is in position for use to raise the cover Z away from the mouth of the tube to continually leave the passage clear for the conveying of the nibs. The tube g preferably enters the plate i, forming the cover, at one end thereof. At the other end is an opening from which projects a tube 0. This tube is the inlet for the compressed air and is of suitable size to freely permit its engagement with the end of the tubing 19.

It is essential that the opening 18 be completely covered when the nibs are being removed and as the size of this opening varies in different machines, I provide an adjustable cover to accommodate a variety of sizes of openings. The plate z' is of a length to fit the smallest size opening. The adjustable means comprises a thin sheet metal frame p slidably mounted between the guides q secured to the bottom of the plate z'. This auxiliary frame p is preferably stamped out in the center to form the frame comprising the side strips r, the rear strip s and the front t of a width to be sufficiently projected beyond the plate z' to increase its length to completely cover the opening 18. The frame 2J being formed The spring end to a hole in the strip 8.

instead of taking the upward curve of the frame is bent downward to aord convenybent slightly out at their free edges u to engage the sides r on the inner sides thereof. Their inner ends are positioned to conf tact with the rear strip s to act as stops to arrest the motion of the frame forward. To retain the frame normally in its foremost position a spring 'v is provided secured to the plate z' as by eyelet w and at its other This strip ient means for securing the spring thereto.

The operation of my extractor is as follows: When sufficient nibs have collected in the chambers of the various machines, the person in charge takes the nib extractor to each machine. Without interfering with the operation of the machine, he places the plate z' over the opening in the machine by first tilting it to the left (Fig. l) to bring the edge of the frame p against the end face a3 of the opening. He then forces the late toward that face against the tension o the spring /0 until the opposite end of the plate is in position to be dropped down to abut against the face y of the opening (or against the adjacent face of the lug 12). The spring o forces the plate and auxiliary frame apart and insures a complete covering of the opening at the ends. On dropping the extractor in position the ring n contacts with the shaft S to effect an opening of the tube at the top. rIhe positioning of the extractor as above described is accomplished by a single movement and the person in charge need use only one hand which preferably grasps the device by means of the cylindrical receptacle. The other hand is free to grasp the rubber tubing 19 which is freely hanging close to the machine. While positioning the extractor the rubber tube is at the same time carried to the tube 0 (the compressed air having been previously turned This is all .done by practically one operation, and ordinarily the rubber tubing need not be slipped over the tube o but only need meet it at the mouth. The air is allowed to pass through for a fraction of a minute, this being all that is necessary to remove the nibs. The pipe is then dropped (the air being turned olf) and my extractor pulled free from the machine by first slightly forcing it toward the end It is then ready to be carried to vanother machine.

If it is desired to use a suction of air instead of the compressed air, the tube o would then be inserted in the receptacle a instead of at the plate z' and instead of the mesh covered opening d the mesh would be placed over the said tube to prevent the possible drawing in of nibs. Moreover there should be an inlet for air in the chamber of the machine7 preferably near the base thereof to agitate the nibs and carry them to the receptacle of the extractor.
